Aluminum substitution in goethite in lake ore [PDF]

Bulletin of the Geological Society of Finland, 1995
The extent of substitution of Fe by Al in goethite in 32 lake ore samples collected from 11 lakes in Finland varied between 0 and 23 mol-%. The data indicated a negative relationship between Al-substitution and the particle size of lake ore.

Effect of Different Aluminum Substitution Rates on the Structure of Tobermorite. [PDF]

Materials (Basel), 2019
Tobermorite and Al-substituted tobermorite with varying Al/(Si + Al) molar ratios were synthesized via the static hydrothermal method. The effect of different Al substitution ratios on the structure of tobermorite was investigated by XRD, SEM–EDS, TG–DSC, FT–IR, 29Si, and 27Al MAS–NMR.

High-Performance Layered Oxides for Sodium-Ion Batteries Achieved through Combined Aluminum Substitution and Surface Treatment

Batteries, 2023
Layered sodium transition metal oxides belong to electrode materials for sodium-ion batteries that combine, in a better way, high performance with environmental requirements. However, their cycling stability is still far from desirable.

Protection of outbred mice against a vaginal challenge by a Chlamydia trachomatis serovar E recombinant major outer membrane protein vaccine is dependent on phosphate substitution in the adjuvant [PDF]

Human Vaccines & Immunotherapeutics, 2020
Chlamydia trachomatis is the most common bacterial sexually-transmitted pathogen for which there is no vaccine. We previously demonstrated that the degree of phosphate substitution in an aluminum hydroxide adjuvant in a TLR-4-based C. trachomatis serovar

Lifecycle assessment of critical material substitution: Indium tin oxide and aluminum zinc oxide in transparent electrodes

Resources, Environment and Sustainability, 2022
Indium tin oxide (ITO) is the most commonly used transparent electrode (TE) material. However, the supply of indium is at risk due to resource scarcity and geopolitical reasons. Aluminum zinc oxide (AZO) is a potential candidate for its replacement.

Ga-substitution effects on the improper ferroelectric phase transition of Ca8[AlO2]12(MoO4)2

Open Ceramics, 2021
The aluminum-sodalite-type oxide, Ca8[AlO2]12(MoO4)2, shows an improper ferroelectricity below a ferroelectric phase transition temperature around 630 ​K. Here we present effects of a Ga-substitution for Al on ferroelectric properties of Ca8[AlO2]12(MoO4)
